Is Rambus Inc. (NASDAQ:RMBS) Expensive For A Reason? A Look At Its Intrinsic Value

Key Insights

• Using the 2 Stage Free Cash Flow to Equity, Rambus fair value estimate is US$46.07
• Current share price of US$57.02 suggests Rambus is potentially 24% overvalued
• The US$78.67 analyst price target for RMBS is 71% more than our estimate of fair value

Today we will run through one way of estimating the intrinsic value of Rambus Inc. (NASDAQ:RMBS) by taking the expected future cash flows and discounting them to today's value. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. There's really not all that much to it, even though it might appear quite complex.

We would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

Is Rambus Fairly Valued?

We are going to use a two-stage DCF model, which, as the name states, takes into account two stages of growth. The first stage is generally a higher growth period which levels off heading towards the terminal value, captured in the second 'steady growth' period. To start off with, we need to estimate the next ten years of cash flows. Where possible we use analyst estimates, but when these aren't available we extrapolate the previous free cash flow (FCF) from the last estimate or reported value. We assume companies with shrinking free cash flow will slow their rate of shrinkage, and that companies with growing free cash flow will see their growth rate slow, over this period. We do this to reflect that growth tends to slow more in the early years than it does in later years.

Generally we assume that a dollar today is more valuable than a dollar in the future, and so the sum of these future cash flows is then discounted to today's value:

10-year free cash flow (FCF) estimate

	2024	2025	2026	2027	2028	2029	2030	2031	2032	2033
Levered FCF ($, Millions)	US$176.8m	US$228.5m	US$265.1m	US$292.2m	US$315.2m	US$334.7m	US$351.4m	US$366.2m	US$379.5m	US$391.7m
Growth Rate Estimate Source	Analyst x2	Analyst x3	Analyst x1	Est @ 10.23%	Est @ 7.85%	Est @ 6.18%	Est @ 5.01%	Est @ 4.20%	Est @ 3.63%	Est @ 3.22%
Present Value ($, Millions) Discounted @ 8.3%	US$163	US$195	US$209	US$212	US$211	US$207	US$201	US$193	US$185	US$176

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$2.0b

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 5-year average of the 10-year government bond yield of 2.3%. We discount the terminal cash flows to today's value at a cost of equity of 8.3%.

Terminal Value (TV)= FCF₂₀₃₃ × (1 + g) ÷ (r – g) = US$392m× (1 + 2.3%) ÷ (8.3%– 2.3%) = US$6.7b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$6.7b÷ ( 1 + 8.3%)¹⁰= US$3.0b

The total value is the sum of cash flows for the next ten years plus the discounted terminal value, which results in the Total Equity Value, which in this case is US$5.0b. The last step is to then divide the equity value by the number of shares outstanding. Compared to the current share price of US$57.0, the company appears slightly overvalued at the time of writing. Valuations are imprecise instruments though, rather like a telescope - move a few degrees and end up in a different galaxy. Do keep this in mind.

Important Assumptions

Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. You don't have to agree with these inputs, I recommend redoing the calculations yourself and playing with them. The DCF also does not consider the possible cyclicality of an industry, or a company's future capital requirements, so it does not give a full picture of a company's potential performance. Given that we are looking at Rambus as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighted average cost of capital, WACC) which accounts for debt. In this calculation we've used 8.3%, which is based on a levered beta of 1.308. Beta is a measure of a stock's volatility, compared to the market as a whole. We get our beta from the industry average beta of globally comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.

SWOT Analysis for Rambus

Next Steps:

Whilst important, the DCF calculation is only one of many factors that you need to assess for a company. The DCF model is not a perfect stock valuation tool. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. What is the reason for the share price exceeding the intrinsic value?
